.To all whom t may concern: n

Be it known that I, EUGENE FULLER, a

citizen'ofthe United States, and resident of vpension for the vehicle which is that of pivoting arocker member on a vehicle element and shackling the end ofthe main spring to 4.said member at a point slightly offset from fits connection to said element,I whereby the spring shackle connections alreadyl on the carfmay be utilized, thus reducing to the o installing such devices. A

A. fui her object ofthe invention lis to provide a lever arm on this interposed rocker member to which a tension .sprin is connected, for the purpose of yielda ly supportingv this rocker and providing additional yieldability to the main spring,

A still further object of the invention is to so arrange Vthe parts that one end of this tension spring may be connected to the main spring.v securing bracket, which bracket is natiirallyso formed as to readily receive the end ci such spring.

A still further object of the invention is to provide means in the lever arm of this rocker member, whereby the tension spring may be shifted so that the efectivo o erating length 'of said arm may be readi y adjusted to accommodate ditlerentlbads.

The invention further consists inthe pro- Y vision of a stop on this rocker mem er for limiting its upward or rebounding stroke.

With theseand other objects in lView, the

invention consists of certain novel features of construction, as will be more fully.v described, and particularly pointed ap ended claims.

n the accompanying Figure 1.-- is an en out inl the drawings i view of a portion of the vehicle showing my improved shock abi sorbing device as applied thereto.

Fig. 2- is anenlarged view of the shock absorbing device showing the rocker niember partially in section and mounted in operative position on the usual shackle bracket used on a certain style of car.

Fig. 3- 's a side elevation of a portion of the rocker member.

Fig. L is a view of the under side of this rocker member showing the shackle bracket in section and showing the oiiset of the 1e'- ver arm. i

Fig. 5 is an end view of this rocker member with the shackles in position thereon b ut with the main `spring removed.

Fig. 6- 1s an end View of the main spring in section on line 6 6 of Fig. l, and showing the bracket which connects the spring to the body bar and showing the naturally formed opening in this bracket adapted to receive the end ofthe tension spring of my shock absorbing device.

The primary object of this invention is the provision of an effective shock absorbing device, and secondly to rovide such a device that is particularly a aptedto be attached to a certain make of car and so arranged as to fit the partsalready on the car and to utilize all of the regularv springsuspension parts, whereby it will/take but a very few moments to position a set of these devices'on a car; and so reduce the cost of the device and the cost of applying the same,

to the very minimum. In accomplishing these (objects, I provide a spring supportingrocker member 10 comprising a ody portion having a pair of downwardly extending ears 11 on its opposite edges adapted to receive the bolt 12 which also passes through the regular standard shackle bracket 13.

The body portion of this'rocker member is also provided with a downwardly extending boss 14 on its front ed e, the same bein of a widthA substantially t at of the len of the hub portion 15 of the shackle b'rf'a'c et 13., This boss is providedwith a boit hole 16 therethrough, which; latter hole is offset slightly from the axis of the bolt 12, both in a vertical and also in a horizontal direction, and through this hole 16 is passed the iop lil

25, one enel of which is proif'iclecl 'Wifh :i

f Leer bolt 17l which also extends through the pair oi' shackles 1S, to the opposite ends of which is connected the eriel 19 oi the main spring Q0 by means of its regular Aboli 2l.

This car ro which lily-device is rlesigneel to he attached is originally oonstrueecl with the shackles 1S hung on the shackle bracket 13, and in order to interpose my rocker memher between it and the main spring and still utilize these shackles Without disturbing their Connection to the .main spring 20, it is necessary that their upper ends be connected es near their original position as possible. Therefore I provide a hole 1G in this rocker for the shackle bolt which is just above and slightly inward from its originel pivoting point, and by cutting away the inner portion of the ears 11 et i-he point 2Q, see Figs. 3 and Li, l provide sufficient room for 1the shackles 'to swing and permit -heiiecessery fielding and elongation of the mein spring 20.

To his rocker member l he ve coimeeteel e. lever arm which extencls both forwardly ariel downwardly therefrom preferably on the are of a circle. This erm is also offset 'lo one siele so es o eleer fthe mein spring y and meer iis enel ii, is provided with a pleroliy of spaced-apart riooh'es 2lon its i31- ner edge to which the teiisioo. ,spring 25 may be ooriiieeizerl.

To install my improved shook absorber' on the parieuler style' of oar for which it is designecl it is only necessary to remove `elle one shackle bolt from its bracket 13.. sind the same bolt through Athese sheohles and hroiigh he hole in the rocker, fllen pass e. new bolt l2 through ears l1 in che rocker miel the shackle bracket, it is .new only necessary to hook one end of bhe tension spring to the bracket 527 and the other enel to the erm enel. ehe job is nished. ialring less than ieri minuies Lo Complete eri iiisialleiioii. l peil of these (levioes may be ooiiiieeerl io e rear.v and a pair on "che reni; spring ii esiieel.
